DURHAM, N.C. — Researchers at Duke University Medical Center say they may have found a gene that could cause male infertility.
Doctors discovered a gene in mice that is involved early in the production of sperm cells. When the gene is missing or defective, it often leads to sterility in mice.
While it has not been proved, doctors believe that is also the case in men. That discovery could lead to ways of correcting the defect and improving a couple's chance of conceiving.
